MARC SOLON, OF TRENTON, NEW JERSEY, ASSIGNOR TO THE POTTERS EQUIPMENT COMPANY, (INC.), OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

DECORATING-KILN ANT) THE LIKE.

Application filed December 8, 1917.

To all whom it may concern Be it known that I, Mano SoLoN, a subject of the King of Great Britain, and resident of Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Decorating-Kilns and thelike, of which the following is a specification.

The object of my present invention is to provide an arrangement of heating fines for a decorating kiln or the like by which there will be secured economy in fuel, a

uniform distribution of the heat, and saving of wear and tear. Another object of my invention is to provide an improved way of supporting the goods within the kiln. These features and others will be described in detail in connection with the accompanying drawings, and the novel features of the invention will then be pointed out in the appended claims.

A typical example of a kiln embodying my improvements is shownin said drawings, Figure 1 being a vertical section of the kiln, taken on line 1-1 of Fig. 2; ig. 2 is a composite horizontal section, the parts to the left of the broken line being in section on line 22 of Fig. 1, and the parts to the right of said broken line being in section on line 2 2 of Fig. 1; Figs. 3 and 4 are vertical sections taken on lines 33 and 1- 4 respectively of Fig. 1, and F ig. 5 is a partial horizontal section on line 5-5 ofFig. 3.

The kiln illustrated is of substantially rectangular form in plan or horizontal section, being provided with a vertical front wall A a vertical rearwall B, and side walls, the lower portions O, O of which are vertical, while their; upper portions are arched to'form' a crown portion O. The front wall A. is provided with a door D for the introduction and removal of the goods to be treated, and at the lower portion of one of the side walls, say O, I arrange a suitable number offurnaces E, of any appropriate construction. Owing to the improved arrangement of heating channels, described below, I am enabled to obtain the desired heating effect with a smaller number of furnaces than heretofore. Thus the two furnaces indicated in the drawing will heat efficiently a kiln of a size which would require four furnaces if constructed accord.- ing to present'practice.

Serial No. 206,150.

The kiln is provided with a bottom F and also with a floor or false bottom G preferably made of tiles and located at a suitable distance above the bottom F so as to leave a space between them. lVithin the kiln, above the floor G and following the curvature of the side and top walls O, O, O, is located an inner wall H, preferably made of interlocking tiles, and spaced from said side and top walls, said wall H extending from the front wall A to the rear wall 13. Partitions J arranged in vertical planes, subdivide the space between the wall H and the walls O, O, O into arched flues K, and L, L. One end of each flue K communicates with the adjacent furnace E, the particular construction shown having a group of three flues K and one flue L, L. The other ends of the flues K communicate with a chamber M, formed below the floor G on one side of a longitudinal vertical partition N which extends from the front wall to the rear wall. On the other side of said longitudinal partition are located heating flues O hereinafter referred to. A transverse' partition N located beneath the floor G separates the chambers M and flues O belonging to different groups, there being one group for each furnace E. The lower end of each flue L communicates with the corresponding chamber M, and the upper end of said flue connects with a smoke flue P in the chimney P, located at the crown fashion and formed by midfeathers of baf fies R, in conjunction with the partitions N, N, side wall O, bottom F and floor G, said baflies extending up from the bottom to the floor. Each furnace E communicates with its group of fines O by means of an opening or channel S.

A transverse partition Q, located at the crown, between the walls O, H, separates the fines L, L of one group from the fines L, L of the other group, and said partition may be extended into the chimney P as shown, to separate'the flues P, P of one group from the fines P, P" of the other group. Another partition Q (Fig. 1) extends within the chimney P longitudinally of the kiln, and down to the upper surface of the wall II, this longitudinal partition separating the fines P from the fines I In the central portion of the rear wall B I locate a heating flue T, having an opening T at the crown of the kiln, to receive aportion ofthe combustion gases, diverted at that point from one of the fines K, and

passing through the flue T, by way of an opening T at the lower end thereof, into the chamberMwhich is adjacent to said rear wall. This diverted portion of combustion fJO the smoke flue P.

heat will be obtained.

gases therefore travels through a by-pass, the main path of the combustion gases from the furnaces B being in parallel through the fines K, first up along the side wall C, then across at the crown C, and then down along the other side wall C, thus reaching the respective chambers M under the floor G, and traveling from each of said chambers through the respective flue L along the side wall G to the smoke flue P. Another portion of the combustion gases travels from each furnace E through the respective channel S into the fines 0 located under the floor G, and passes from said flues upwardly along the side wall C, through the flue L to It will be seen that in this manner I conduct heating gases around the kiln chamber at practically every side Thus the increased ratio of wall surface to,

gas volume secured for the relatively cooler gases will, as it were, bring a larger number of gas particles, per unlt of time, into contact with the respective portions of the kiln walls, and a thorough utilization of the 7 Another, feature which I prefer to employ for the same purpose, consists in making the inner wall H of a thickness reduced gradually in the direction inwhi'ch the combustion gases travel along said wall in the fines K. The conduction of heat through the wall II will therefore takeplace through progressively thinner wall portions as the temperature of the gases in the lines K decreases.

. For convenience in construction, the fines L, L are given the same shape, in cross section, as theadjacent portions of the fines K.

Another feature of my invention consists in the manner of supporting the bats or like bases, containers, etc.,- which receive the .goods. under treatment. Forgthis' purpose,

I have shown posts U located on the floor G at points vertically above the midfeathers or bafiies It, with I beams V 'carried by said posts and extending transversely to the direction of said baffles. These beams preferably have their upper surfaces in the same horizontal plane, and are adapted to support the iron bats W or the like carrying the ware. It will-be seen that with this arrangement the weight of the ware is supported virtually by the bafiies R, and the floor G is practically relieved of the func tion of sustaining the weight of the ware, so that a comparatively thin (tile) floor may be employed.

It will be understood that in the particular construction shown, the combustion gases travel within the kiln walls, as it were, or around the kiln chamber, that is to say, said gases do not enter the chamber containing the ware. p v p Various modifications may be made with out departing from the nature of my inventionas set forth in the appended claims.

I claim; q

1. A kiln provided with walls and heating flues in opposite walls, said flues having a heat-supply-connection and an outlet connection, and a by-passheating flue located in one of the other walls and having its upper end connected with a point of the other fines relatively near the supply connection, and its lower end connected with said flues at a point relatively near the outlet connection. a
